A US woman who shot and killed her husband and two adult children before taking her own life is thought to have committed the shocking crime as a result of being ostracised from the religion she was raised in.

Every time I tell a mate I’m doing a story on cryptocurrency, they invariably ask me the same two questions: should they invest their own hard-earned money, and which cryptocurrency will get them a Lamborghini/yacht/island quickest?

WA premier not swayed by wage protesters

West Australian Premier Colin Barnett says while he is "sympathetic" towards workers on lower wages in the public sector, he will not be swayed by protesters.

Hundreds of health and education support workers rallied outside the premier's office on Wednesday demanding a higher wage increase after the state government offered them a rise of $22 a week.

United Voice has been negotiating with the Health Department on a new wage deal for hospital support workers since May, and with the Education Department for a new wage deal for school support workers since August.

The premier said both government departments were bargaining "in good faith" with a view to providing workers with fair wage increases.

"Negotiations for hospital workers are now taking place before the WA Industrial Relations Commission, which is assisting the parties in trying to come to an agreement," he said.

"These negotiations are not being assisted by an overtly political campaign by United Voice alleging that the government has some secret privatisation agenda.

"This is despite assurances provided to the union confirming there are no such plans."
